Tinicum
MediumFirm Overview
Tinicum manages a diversified group of manufacturing, distribution, industrial technology and specialty infrastructure companies. The firm focuses on controlling interests in private companies, seeking to identify entities that merit indefinite ownership as core holdings.
Tinicum traces its heritage back to its founder, Derald H. Ruttenberg, who started investing in the 1940s. In 1974, Mr. Ruttenberg founded Tinicum to invest as a private individual, and the firm began managing outside capital in a traditional private equity fund structure in the 1990s. In 2012, the firm established Tinicum L.P., a long-term investment vehicle with an indefinite life and multiple, successive commitment periods.
The firm applies deep industrial experience to develop enduring franchises by strengthening organizations, winning customers, introducing innovative products, expanding into new markets, improving operations and acquiring complementary businesses. Tinicum avoids overreliance on cost reduction, debt repayment and other financial engineering, preferring instead to invest in businesses with strong market positions and capable management.
Tinicum manages $5.2 billion of assets, principally comprising commitments from families and individuals. The firm aims to be a constructive, value-added owner whose professional skills and relationships complement those of operating managers, often partnering with founders and families to build businesses for the long term.
